trust me on this one , folks --us military (union) civil war era artillery nco or officers pin --collar or hat device (which one not sure of ) -- company "c" --the letter at bottom is the company - the uppper numbers are the unit number -- it 's got a "0" --so its the 10th , 20th ,30th,40th . 50th, 60th ,70th, 80th or 90th with the first "number" sadly being lost * - looking at the lead shot type items that were found with it --they are all us military civil war eraish type lead bullets -- so logically speaking -- in my veiw its a civil war eraish us military artillery item --since artillery swords were only issued to nco's and officers logically speaking --its most likely a officers item * --crossed cannons type devices were for the artillery enlisted men who served as gun crew.
